| 摘要 |
In one aspect of the invention, a display includes a substrate, and a plurality of pixels formed on the substrate and arranged in an array. Each pixel has a driving transistor having a gate electrode, a drain electrode and a source electrode, formed on the substrate, an organic light emitting diode (OLED) having a cathode layer, a anode layer and an emissive layer formed between the cathode layer and the anode layer, and formed over the driving transistor such that the anode layer of the OLED is electrically connected to the source electrode of the driving transistor, a bias electrode formed over the substrate, and a photo sensor having a photosensitive layer formed between the anode layer of the OLED and the bias electrode. |
